Founding Engineer

About Muro AIMuro AI is transforming how the $2T construction industry plans and builds. Founded by Cornell alumni, ex-founders, and former McKinsey operators, we’re building AI agents that automate the most complex, manual, and costly phase of construction: preconstruction.We move fast, build with conviction, and obsess over delivering real impact to the people who build our world. If you want to shape how the next century of construction gets built, this is where it starts.Who You AreA true builder with 4+ years of technical experience. You’ve lived the 0→1 chaos - maybe you co-founded something, or led a team through the trenches. You know that the good (fast growth) and the ugly (2 AM patches) come with the territory. You’re scrappy, curious, and energized by uncharted problems.Why It MattersShape a category. No one owns “pre-con AI” yet — we’re charting that map.Bridge two worlds. Effect changes in an estimator’s spreadsheet with multimodal models that understand construction documents.Drive impact. Your AI agents will help contractors close multi-million-dollar bids and save hundreds of hours per project.Your MissionBuild agentic workflows that work. Create agents to complete multi-step construction tasks. Implement tool use for Procore APIs, Excel manipulation, and document generation. Build agents that read plans, update budgets, and generate RFIs autonomously.Ship production RAG systems. Process 1,500-page plan sets. Build pipelines that understand construction specs and drawings. Handle messy, real-world documents - scanned, rotated, hand-marked. Deliver semantic search that actually finds the door schedule on page 347.Embed with customers. Sit with estimators during bid week. Understand workflows, then turn “we manually compare 50 subcontractor bids” into an intelligent agent.Own the AI stack. Python services orchestrating model calls. Celery workers for long-running jobs. Vector DBs for semantic search. Context engineering, evaluation frameworks, and monitoring for quality. Dockerized workloads on GCP infra.Make AI reliable. Build evaluation datasets from real construction docs. Collaborate with SMEs to catch hallucinations and make models accurate enough for million-dollar decisions.Tech StackAI/ML: LLM APIs, Agentic frameworks, RAG pipelines, Vector DBs, LangfuseBackend: Python (FastAPI), Celery, Node.js/TypeScriptInfra: GCP, Docker, SupabaseData: PDF parsing, spreadsheets, computer vision, unstructured data pipelines Who Should ApplyWe want hands-on builders with 4+ years of experience delivering applied AI to real users. You might be:A Full-Stack Engineer hacking with LLMs who wants to go deeperA Forward Deployed Engineer who wants to build AI, not just integrate itAn ML Engineer who wants to ship products, not just modelsA Data Scientist tired of notebooks who wants to ship production codeA Founding Engineer or ex-CTO ready for the next challengeYou'll Stand Out If You HaveBuilt and deployed an AI feature with real usersAEC industry experienceWorked with computer vision or advanced OCR pipelinesFine-tuned a model with a custom-built datasetsRoles involving coding + customer interaction (FDE, Solutions Engineer, etc.)Prior founding-team or 0→1 experienceReal TalkYou’ll own customer and agent implementations end-to-end.You’ll ship to production within days, not weeks.Specs will be half-baked - you’ll fill in the blanks.You’ll wear many hats: dev, architect, product, recruiter, and support hero.If you love making AI solve real problems for real people, you’ll thrive.Location: In-person in San Francisco. Will cover relocation costs. Compensation: $140K – $220K base + competitive equity + full benefits package
